By now it should be no surprise that HDTV unit sales doubled in the fourth quarter of 2006 compared to 4Q 2005. What might lift an eyebrow is that a third of those bright shiny new HDTVs were 1080p models, according to Pacific Media Associates. Just six months earlier, 1080p had accounted for only five percent of HDTV sales. What a change half a year of hype can make. For the alphanumerically disinclined, "1080p" refers to displays that show 1920 by 1080 pixels with the entire picture drawn one full frame at a time. Back when guys delivered chunks of ice to cool cordless refrigerators, analog television began using an interlacing process that scanned each frame in two passes, and this process still survives, sort of like the coccyx. However, some experts point out that paying a premium for 1080p may not be a wise decision. Notes our video editor Geoff Morrison: "From where most people sit, you don't need 1080p in a 37-42 inch TV. It's arguable that you do in a 50-inch set." Deal of the month: Buy one Pioneer Elite PRO-FHD1 50-inch plasma, get one free. Next big thing: the 120Hz refresh rate.
